Merging Files with similar structure but removing duplicate headers

I often get text files of similar type (Tab delimited, CSV, etc.) but they all have a header row.  A super easy way to merge the data together is to

1. Created a folder that only has the files you want to merge
2. create a command prompt in the directory
3. use the following dos command to merge the files (adjusting the extension to your purpose:  copy *.csv  merged.csv

This will merge all of the files ending in .csv into the merged.csv file however it keeps all the header rows. :(   This annoyed me so I wrote a short program to use AutoHotkey and only keep the first header row.
